Hóčha, the other day someone asked me if I always spoke in Lakota ( wish I could
) People generally don't have time for me to figure out verbs and rack my brain for vocab. If anyone speaks to you in Lakota do give them time I have plenty of words and sentences I can say instantly.
I call most people šič'éši / čépȟaŋši.I say it's really traditional but actually as well it gets me out of an awkward spot when I can't remember a name

I often use
Tóškhe yaúŋ he ?/ How are you? (colloquial Oglála)
Heaps of other ways also available

My fav quick greetings include -
Taŋyaŋ́ waŋčhíyaŋke / It's good to see you.
Iyúškiŋyaŋ waŋčhíyaŋke / I am happy to see you.
Taŋyáŋ átačhiye/ It's good to meet you.
At the doctors the other day my first 5 quick sentences were in Lakota including čhaŋkpé mayázaŋ / My knee hurts.
All went well until he stabbed an enormous needle into my knee, "AGH!!!!! Yúŋ,yúŋ,yúŋ.Haúŋ,haúŋ,haúŋ!!!!!
The doctor said I was the first person to speak any Native American language to him. That's sad as there are heaps around but there soon won't be unless we all SPEAK IT
Don't put it off, speak right now
Tókša
